Design Science License

Hello,
I am creating a power point slide show to use in training apprentice electricians, and was wanting to use pictures and some text from the textbook, "Lessons In Electric Circuits, Volume I - DC". What do I need to do to comply with the Design Science License in this case? I will not be distributing the slide show, I will simply be using it to present information to a classroom of students.

I was thinking of including a little symbol in the lower left corner of any slide that uses information from this publication and having a notice at the beginning of the presentation that would let the students know where the information came for those slides. I would also have a slide that showed where they can access the full text of the publication as well as the design science license on-line. Would that be sufficient?
